I have decided its time to up my cars power to stage three as my standard turbo is at the end of its life, i have the injectors etc but no turbo or chip, i know most people fit a t34 with a .48 housing is there any other options have had a t35 mentioned but not sure what the difference between a 34 and a 35 is cheers

Different people call them different things, but to most a T34 and a T35 are the same thing.
A T34 is a large turbo escort cossie size.
You would do well to consider having basic mods done at the same time as new or rebuild, such as a 360 bearing is a must for longer life than the std 270 affair.
The turbine housing size will have a major influence/impact on how it drives, ie smaller boost earlier, but ultimately won't produce as much power, but if it's doing as much as you want power wise then a smaller one makes a nicer car to drive all the time, especially off boost.
You could go roller bearing for even less lag, but price is a lot more, so consider carefully the characteristics you can live with, for me I like it in nice and early so it is better off boost, so have a .48 housing, I have a T34 compressor trim in a machined out T3 housing, works well for me.

have you got a rs500 type cooler though? Cos you'll need one if you don't have one depending on the boost you run
